The purpose of this work was to present the cinglulum
bundle located above the corpus callosum. It consists of a complex white matter
fiber tract of the human brain that comprises long association fibers,
commissural fibers, and various U-fibers. The fiber tractography was achieved
by diffusion tensor imaging using a single-shot STEAM-sequence with 24 gradient
directions at 1.8 mm isotropic resolution. In order to map the full cingulum
bundle 41 oblique sections in AC-PC orientation were acquired without gaps in
an interleaved order.
